Find the luminal surface and estimate the proportion of the uterine wall occupied by the endometrium. The appearance of the endometrial glands, the stroma, and the blood vessels in the endometrium indicate that this tissue represents the secretory stage of the uterus. How would you characterize the muscle pattern of the myometrium? REFERENCES: Ross, pp. 699, 722 - 725 Gartner, pp. 243, 352-355 Wheater, p. 348 DiFiore, pp. 308 - 309 |

Red arrow - Endometrium Blue arrow - Myometrium Yellow arrow - Endometrial glands of luteal phase
This is a closer look at the Endometrium of a uterus in the secretory or luteal phase of the ovulatory cycle. Notice the characteristic shape and size of the Uterine or Endometrial glands (blue arrows) which are very numerous, elongates to stretch the length of the endometrium and have the characteristic "spiral" or "corkscrew" appearance. When ever you see these characteristics, you can safely say that the uterus is in it's secretory phase. Blue arrows - Uterine Glands of Luteal Phase
This is a high magnification shot of the Uterine Glands during the secretory phase of the ovulatory cycle. Emphasizing the "sprial" or "cork screw" characteristic shape of them during this phase of the cycle.
Blue arrows - Uterine Glands of Luteal Phase |
This is a image of the Uterus, again showing the two layers being the Endometrium, indicated by the red arrow, and the Myometrium indicated by the blue arrow. This image is taken from the a uterus in the Luteal or Secretory Phase of the ovulatory cycle. We can tell this by the characteristics of the Uterine Glands (yellow arrows). Here they are elongated and stretch the entire length of the endometrium, "corkscrew shaped" and very numerous. This is the characteristics of the uterine or endometrial glands in the uterus during the secretory or luteal phase.
